5 Most Common Dishwasher Problems

Imagine how difficult it is to get someone in the family to load the dishwasher properly or simply to switch a button for the loaded dishwasher to run…

Now imagine getting one of them to do a load of dishes!

This is an unimaginable task to many mums (well… most anyways!)

Understanding these problems and knowing how to fix them can save you both time and money.

Keep reading to find out what the dishwasher repair experts listed as the five most common dishwasher problems and detailed steps on how to fix them.


1.Dishwasher Not Draining Properly

Usually, you might notice that the water is pooling at the bottom after a cycle or slow or incomplete draining might indicate a clogged filter or drain hose, faulty drain pump or a blocked garbage disposal (if connected).

These are the easy fixes if your dishwasher is not draining properly:

  1. Check and Clean the Filter (if necessary) and this is how you do it!

– Locate the Filter: In most dishwashers you just have to open it and check the bottom beneath the lower spray arm.

– Remove and Clean: Unscrew or unlock the filter. Rinse it under warm running water, using a soft brush to remove debris and buildup.

  1. Inspect the Drain Hose:

– Check for Kinks or Clogs: Trace the drain hose from the dishwasher to the sink drain or garbage disposal. Ensure there are no sharp bends or visible blockages.

– Clean the Hose: Disconnect the hose and use a long brush or a plumbing snake to remove any clogs.

  1. Examine the Garbage Disposal:

– Clear Obstructions: If your dishwasher drains through a garbage disposal, ensure it’s not clogged. Run the disposal to clear any blockages and check the knockout plug.

  1. Test the Drain Pump:

– Listen for Noises: During the drain cycle, listen for any unusual sounds from the pump, which could indicate a malfunction.

–  Professional Help:  If the pump is faulty, it might need to be replaced by a professional dishwasher repair technician.

2.Dishwasher Not Cleaning Dishes Properly

There is the reason why mums usually shout not to load the dishwasher with food leftovers! If the dishes are not clean after the washing cycle if you noticed cloudy or greasy residue on glassware and utensils, it could possible due to dirty spray arms, low water temperature or incorrect loading of dishes.

Let’s try the following before you rush to dishwasher service in Melbourne.

  1. Clean the Spray Arms:

– Remove the Spray Arms: Depending on your model, unscrew or unclip the spray arms from the dishwasher.

– Rinse Thoroughly: Rinse the spray arms under warm water. Use a toothpick or small brush to clear any clogged holes.

  1. Check Water Temperature:

– Adjust the Water Heater: Ensure your water heater is set to 120°F (49°C) for optimal cleaning.

– Run Hot Water:  Before starting the dishwasher, run hot water in the kitchen sink to ensure the dishwasher starts with hot water.

  1. Load Dishes Correctly:

– Avoid Overcrowding: Arrange dishes so that water can circulate freely. Place larger items like pots and pans at the sides and smaller items like glasses and plates in the center. (Just like how your mum yelled at you!)

– Face Dishes Correctly: Ensure all dishes face the center of the dishwasher where the spray arms can reach them.

3.Dishwasher Making Unusual Noises

This is what grinding, humming, or knocking sounds during operation could mean obstructions in the spray arms or pump or loose components inside the dishwasher.

What could we do to fix it?

  1. Inspect the Spray Arms:

– Check for Obstructions: Remove the spray arms and check for food particles or other debris that might be causing noise.

– Clean and Reattach: Clean the arms and ensure they are securely reattached.

  1. Tighten Loose Components:

– Secure All Parts: Inspect the interior of the dishwasher for any loose screws or bolts, particularly around the spray arms and the door.

– Test the Racks: Ensure the racks are properly seated and not causing noise during the cycle.

  1. Examine the Pump

– Listen for Irregularities: Unusual sounds from the pump area might indicate a need for professional inspection.

– Professional Repair:If the pump is determined to be the issue, it might require professional servicing or replacement.


4. Dishwasher Door Not Closing Properly

If you noticed the door doesn’t latch or seal correctly or water is leaking from the door during cycles, it could be a misaligned door latch or a damaged or worn door seal.

You could try the following solution but do not force anything on the machine as it could cause more harm to it! Make a quick trip to the closest dishwasher repair center!

  1. Adjust the Door Latch:

– Realign the Latch: Check the latch alignment and adjust it if it’s off-center. Tighten any loose screws that may have shifted.

– Test the Door: Close the door to ensure it latches securely and evenly.

  1. Replace the Door Seal:

– Inspect the Seal:Examine the door gasket for signs of wear, cracks, or deformities.

– Install a New Seal: Purchase a replacement gasket specific to your dishwasher model. Remove the old seal and press the new one into the groove, ensuring it’s seated evenly.


5.Dishwasher Leaking Water

Water leakage during or after a cycle or if you notice that water is pooling around the base of the dishwasher, perhaps it could be due a damaged door gasket, loose or cracked hoses or a faulty float switch.

These are the simple solutions you can try to fix your leaking dishwasher.

  1. Inspect the Door Gasket:

– Check for Damage: Look for any tears or gaps in the gasket around the door.

– Replace if Necessary: If damaged, replace the gasket to ensure a watertight seal.

  1. Examine Hoses:

– Check Connections: Inspect the water inlet and drain hoses for any signs of cracking or looseness.

– Tighten or Replace: Tighten loose connections and replace any damaged hoses to prevent leaks.

  1. Check the Float Switch:

– Ensure Proper Movement: The float switch prevents the dishwasher from overflowing. Make sure it moves freely and isn’t stuck.

– Replace if Faulty: If the float switch is malfunctioning, it may need to be replaced by a professional.

Proper usage and regular dishwasher maintenance could prolong the lifespan of the dishwasher and also maintain its efficiency!

Be very cautious when you are trying to fix by yourself because you could end up doing more damage to the dishwasher. Ensure that you seek professional help whenever necessary. The golden rule in using a dishwasher is – listening to your mum!
